Sunan an-Nasai Book 43, Hadith 4410

أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ أَنْبَأَنَا يَحْيَى بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا سُفْيَانُ، قَالَ حَدَّثَنِي أَبِي، عَنْ عَبَايَةَ بْنِ رِفَاعَةَ، عَنْ رَافِعِ بْنِ خَدِيجٍ، قَالَ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّا لاَقُو الْعَدُوِّ غَدًا وَلَيْسَتْ مَعَنَا مُدًى ‏.‏ قَالَ ‏"‏ مَا أَنْهَرَ الدَّمَ وَذُكِرَ اسْمُ اللَّهِ عَزَّ وَجَلَّ فَكُلْ لَيْسَ السِّنَّ وَالظُّفْرَ وَسَأُحَدِّثُكُمْ أَمَّا السِّنُّ فَعَظْمٌ وَأَمَّا الظُّفْرُ فَمُدَى الْحَبَشَةِ ‏"‏ ‏.‏ وَأَصَبْنَا نَهْبَةَ إِبِلٍ أَوْ غَنَمٍ فَنَدَّ مِنْهَا بَعِيرٌ فَرَمَاهُ رَجُلٌ بِسَهْمٍ فَحَبَسَهُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ إِنَّ لِهَذِهِ الإِبِلِ أَوَابِدَ كَأَوَابِدِ الْوَحْشِ فَإِذَا غَلَبَكُمْ مِنْهَا شَىْءٌ فَافْعَلُوا بِهِ هَكَذَا ‏"‏ ‏.‏

It was narrated that Rafi bin Khadij said:"I said: 'O Messenger of Allah, we are going to meet the enemy tomorrow, and we do not have any knives.' He said: If the blood is shed and the name of Allah is mentioned, then eat, unlike (it is slaughtered) with teeth or nails and I will tell you about that. As for teeth, they are bones, and as for nails, they are the knives of the Ethiopians,; We acquired some spoils of war including sheep or camels, and a camel ran away, so a man shot an arrow at it an stopped it. The Messenger of Allah said: 'some of these animals' or 'these camels'- 'are untamed like wild animals, so if one of them goes out of your control, do the same." (Sahih)
